DECATUR, Alabama -- Police this morning shut down the Highway 31 bridge over the Tennessee River in Decatur searching for a suspect who led them on a chase, fired multiple shots at police, then climbed up onto the upper structure of the bridge.

At about 9:05 A.M., 40-year-old James Huber gave himself up to police after holding police at bay with a gun for more than six hours, said Lt. John Crouch with the Decatur Police Department.

He was being taken to Huntsville Hospital to be treated for hypothermia, then will be charged, possibly with attempted murder charges, by the Madison County Sheriff's Department. Decatur police will file additional charges, Crouch said.The bridge was reopened for traffic shortly before 10:30 a.m.Madison County and Morgan County deputies, Decatur police, Alabama state troopers and Marine police were on the scene with boats and a helicopter.

The situation began just after 3 a.m. when Madison County deputies attempted to pull over a suspicious vehicle, which fled, leading them on a high-speed chase in which the suspect fired at the deputies' vehicles, Crouch said.

The suspect, who was driving westbound in the eastbound lanes of I-565, abandoned his car on the bridge, and fired more shots at police, Crouch said.

Crouch said the suspect, who has not yet been identified, has an extensive criminal record with multiple felony convictions.
